Investigators: Homeowner shoots worker, turns gun on self

LONDONDERRY, N.H. (AP) — A New Hampshire man fatally shot a heating oil company employee who came to his house to do work before trying to kill himself and engaging in an hours-long standoff with police, authorities said.

"What looks like happened is, the homeowner shot a person who came into the home to perform some services, and then he turned the gun on himself, so it looks like it was an intended murder-suicide," said Senior Assistant Attorney General Jeffery Strelzin.

Police and SWAT team members responded to the home in Londonderry on Tuesday. The neighborhood was evacuated and several schools were placed on lockdown due to the police activity in the area.

Neighbors told police that a City Fuel van pulled up to the home and they heard gunfire a short time later. Investigators said the employee was killed. The homeowner was taken to a hospital in Massachusetts, where he was listed in critical condition.
